Solve the triangle. b = 73°, b = 15, c = 10

Incomplete Question, the complete question is

Solve the triangle.

B = 73°, b = 15, c = 10  

A. C = 39.6°, A = 67.4°, a ≈ 14.5

B. Cannot be solved

C. C = 44.8°, A = 62.4°, a ≈ 14.5

D. C = 39.6°, A = 67.4°, a ≈ 20.3

The Answer is the option A

A. C = 39.6°, A = 67.4°, a ≈ 14.5

Step-by-step explanation:

Given:

In Δ ABC,

∠B = 73°

b = 15

c = 10

To Find:

∠A = ?

∠B = ?

a = ?

Solution:

IN Δ ABC,  Sine Rule says that

Substituting the given values we get

Triangle sum property:

In a Triangle sum of the measures of all the angles of a triangle is 180°.

∴

Substituting the given values we get

∴

Therefore,

A.  ∠C = 39.6°, ∠A = 67.4°, a ≈ 14.5

a. is correct

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17
